CONSECUTIVE-PRINTING A PARATUS. I

To all whom it may concern Be it known that 1,. JOHN G; JONES, a citizen of the United States of America, residing at Rochester, in the county of Mon roe and State of New York, have invented certainn'ew and useful Improvements in Consecutive-Printing Apparatus, of which the following is a full, clear, and exact specification.

This invention relates to apparatus for printing on sensitive photographic material, and more particularly to. apparatus for light-printing consecutive symbols thereon. The general objectof my invention-is to provide an improved broad combi ""t l f elements, as well as certain mproc combinations, which will operate accui ately, rapidly, reliably;and efficiently on large- Anothcr object of terial in progressively decreasing order so that, when the numbered material is wound up, the lowest numbers will be on the outside of the roll; in which a novel lighting system is provided including reflecting devices for properly directingthe, beams of light; in which printing members of novel construction are employed together with operating mechanism, permitting them to be: independently, manually and rapidly adjusted to their zero or starting positions; in which an lmproved shutter-"1s embodied; 1n which a anovablc Presser-foot is so' actuated as to positively press the sensitive material toward the printing members; in which the speed of operation of the shutter and resser-foot can be varied;-and'in which the several parts are all driven in properly timed relation. Further objects will hereinafter appear.

My invention at present finds its most important application in theprinting of consecutl've numbers, atr'egular mtervals along one edge of unexposed motion picture nega- I Specification of Letters Patent.

My invention. is particularly convenient when used in connection with a machine for perforating the edges of motion picture film, and I have, therefore, illustrated it in such connection, but it is understood that it may be used alone-or with any machine which advances the film in proper relation to the movement of the rest of the apparatus. In Fig. 2 I have shown in unshaded' perspective a Bell and Howell film perforating machine A which is typical of such perforators, uponwhich is mounted my apparatus denoted generally by B. In the perforator the film passes from a supply reel 1 over idlers 2 and driving wheel 3 through the apparatus 13 beneath the punches s through pads 5, over sprocket 6 and idlers 7 towinding reel 8. In the bed 9 of the perforator is an intermittent film feed of standard type moving in timed relation'to the continuously rotatin sprocket G and wheel 3. The latter wheel and its idlers 2 are cut away as shown in. Fig. 1 to avoid contact with the sensitive face of the film.

AshaftlO which carries wheelB is used to support the main frame 11 of my apparatus. The frame is supported on the shaft 10 by bearings 12 at each side of a gear box 13' on the perforator. shaft 10 is driven from cross shaft ll of the perforator through beveled gears 16, shaft 1 1 being located in hollow arm 15;

' of gear box 13, the plate having spaced perforations 18 in which is received the end As shown in Fig. 1,

of a sliding pin 19 on frame 11. The apparatus normally rests in the position shown in Figs. 1 and 2, but if it is desired to perforate-the film without numbering it, pin 19 is removed from the lower opening 18 and the apparatus swung upwardly until 19 can be inserted in the upper hole 18.

The film after leaving wheel passes in a loop 20 to the pathway of my apparatus,

best shown in l igs. at and 15. This pathway comprises plates 21 having narrow supports 22 at each side for engaging the edges only of. the film. The central portion of plates 21 is depressed at 23 so as to be out of contact with the sensitive surface of the film and particularly the picture areas thereof. Of course, the sensitive surface of the film is.downward toward the light printing opening 2st formed in one side of the pathway in line with one of the supports 22... The entire apparatus is used in a dark room and the only actinic lightwhich can affect the film issues internally through opening 24: from the illuminating system, hereinafter described. Consequently, the pathway shields all of the fihn from light action except a narrow section at one edge which lies outside the picture areas. The depression of 'the central portion 2? is generally sufii cient to avoid abrasion .ot the film, but as an additional precaution in my preferred device I mount centrallyot' the plates '21 a series of rolls \vhlch gne practically frictionless support to the center part of Figs. At and 15. In one of the supports 22 I may also form an additional opening 27 receiving a stationary plate 28 bearing a.

light transmitting image or word which w1ll be-impressed upon the film at each pr1nt1ng operation.

In the opening 24:, however, I provide a serieSof relatively movable printing members or elements 29 each bearing a set of images. of the symbols ornumerals to be printed. These elements .are in tubular or ring form and are provided with peripheral plane facetsSO best seen in Figs. 16 and 19. Leading to alternate facets, are radial openings 31 in which are.located plates 32 bearing light transmitting images 321, either negative or positive, of numerals or other symbols to be printed. Alternating with these light transmitting images are plates 33 bearing observation images 3.31,.duplicating or corresponding to images 3211, but regiularly spaced therefronr Thus, in the pre ferred form of my apparatus each observation'numeral isspaced about 90 around the ring from the corresponding light transmitting printing numeral. See, for example, numeral 2 in Fig. 16. images are opaque in my preferred form.

These observation Rings 29 are mounted on flanges 34 of" gears 35, the flanges being perforated at 36 in alinem ent with openings 31. These assembled gear and ring units are co-axially mounted upon a tubular bearing 37 (Fig. 11) provided upon its upper-portion in alinement with opening 24 "with a set of light'transmitting areas or perforations 38 these perforations being of a size and location to aline with selected-openings 36 and 31 in the gear flanges and rings. .The bearing, and therefore the axis aboutwhi'ch the tubular members turn, is. substantially parallel to the p-atlrof movement of the film,

- and, consequently; the printing'm'einbers 29 move in planes which extend laterally or transversely of the pathwayof the film.

Each element-29 is driven by its individual gearing. Upon shaft 39; below and parallel to bearing 37, are rotatably mounted a series of gears 40, one meshing with each gear Shaft 39 is supported in bearings 391. Attached to eachgear 40 is a ratchet. wheel 41 for driving the same. Upon theo'pposite side of each gear 40 is attached a pawl shield 42 having a single depressed 1')ortion;43;.best-seen in Fig. 23.

A yoke 44 is fastened on shaft 39 to oscil late therewith and carries upon a transverse rod 45 a series of pivoted pawls 46 for driving ratchets 41, said pawls being pressed toward said ratchetsby springs 47 held in placeonyoke 44 by plate 48. All the pawls 46 which enter between the gears 40 are of sufficient width to simultaneously engage both a ratchet 41 and pawl shield42. The tail 49 of each pawl 46 carries a short rod 50 which engages in a depressed portion 51 in the tail of the next adjacent pawl (see Figgflb), thus forming adirect connection between them. a stationary rod 52 upon which are pivotally 'nieunted a series of retaining pawls which are pressed by springs 54 against the nitellets 41 to prevent the latter from turn- .-.1ng' backward or clockwise in Fig. 28, said ratchets have special sockets into which ,the noses of pawls 53 drop, so that the images on rings 29-will be inexact alinement in opening 24 and so that the corresponding facets will he substantially in the same plane. 4

'In the illustrated preferred form, each ring bears a set of numerals, 0 to 9 inclusive. At the start the Os may be alined as' shown in Fig.4, or the 9s may be alined in case the apparatus is set to operate the printing members from the highest number down' ward, such a setting being-effected by re versing the rings 29 on flanges 34. The latv ter arrangement has the advantage that the numbers which are printed upon the edge of the film (at one foot intervals, for eX- ample. if the feed is adjusted for that spac- Atone side of shaft 39 is' ing j will decrease consecutively down to. 1,

thus bringing the smallest numeral upo ptheoutside of the film roll and avioiding the necessity of either rewinding it for using the numbers backward y W lVhen the desired starting numerals are in alinement in'opening24, the plane facets 30 being also substantially flush with the surface of support 22, the pawl shields 42 will be so positioned that the depressed portions 43 are just beyond the operative strokes of pawls 46. Each ratchet wheel is provided with 10 teeth,therebyrequiring 1O operative impulses from its pawl't o turn it step-by-step through the standafd distance to change the numerals.

Every time that theyoke44 hnakes a. working stroke, the left hand pawl 46 in Fig. 26 will drive its ratchet through, a step corresponding to one tooth. Through gears 40 and 35, the first ring 29 will be correspondingly moved to present a dilferent numeral in opening 24. Dnringeach of the first nine strokes. t he re-inaining pawls 46 will ride upon the curved' faces of shields 42 and so cannot engage their corresponding ratchets 41, being thus retained in inoperative position. Upon the'tenth stroke, the depressed portion 43 pf the first or left hand pawl shield 42 wi lcome beneath the second pawl 46 and thusthe latter can enter the second ratchet 41 and advance it onestep, thereby changing the corresponding numeral oh the second ring 29. Dining the eleventh stroke.

the depressed portion 43 of the, first paw-l shield 42 will be moved out of reach of] the second pawl and the latter will idly reciprocate until said first shield has again been advanced tensteps. When the hundredth actuation takes place, the second gear 40 and its attached pawl shield 42 will have moved through ten steps. (one step at the tenth, twentieth; thirtieth, etc., ,strokes) thereby bringing the depressed portion of the second shield 42 into the path of the third pawl 46 and permitting the latter to.

operate the third ratchet through one step. thus changing the numeral on the third ring 29. a

uring the hundred and first to the-hundred and ninth strokes, the depression 43 of the second pawl shield will remain beneath the second pawl 46 so the latter, if unrestrained, could rotate he third ratchet at each stroke. This is du to the fact that the second gear and'consequently thev second shield is moved only one step at every tenth stroke. Clearly, if the third pawl could thus drive the third gear at every stroke from the hundred and first to the hundred and ninth, the necessary consecutive numbering would not take place. To guard against this, pins 50 are provided. Each pin holds the next adjacent pawl in inoperative parts are driven unidirectionally.

in this one direction.

sllCll that each gear 40 may be turned by' position so long as its own pawl. remains in inoperative position. Consequently, the pin on the second pawl is will hold the third pawl in inoperative position from the lumdrcd and first to the hundred and ninth stroke, said second pawl being itself held inoperative by the first pawl shield. By extending this analysis it will be found that the pawl shields 42 and the pins 50 together insure that all the numbers 'will appear in opening in consecutive order.

The numbering devices hereinabove described are contained in a chamber 56 ha'viug a movable rear cover 57 and two openings and 59 in its front plate 60,the latter also, being removably held in place by screws. Opening 58 is located laterally of the bearing 37, as bestindicated in Figs. 3 and 15, and is closed by a transparent win dow 61 through which may be observed an alined set of observation numerals 331 which are duplicates of'the corresponding printing numerals 321 which appear at the same time in opening 24:, the two sets of numerals being spaced for this purpose as hereinabove stated.

It will be noted that the teeth on ratchet 41 as well as the sockets 55 and the cooperating pawls 46 and are all so shaped that the ratchcts together with their attached' They-are alsoindependently and manually movable The construction is hand, pawls 4G and 53 slipping from tooth to tooth and socket to socket during such manipulation. In this .way a fractional r0- tation of each gear 40 and consequently 0 each ring29 suffices to quickly set the whole apparatus back to Zero or starting position. Opening 59 permits the operator to introduce a tool for suchmanipulation; It is normally closed by a pivoted door 62.

Inside the tubular bearing 37 is a tubular shutter 63 provided with longitudinal slots (H and 65 designed to come successively into a'linement with perforations 38 in bearing 37 which are themselves in line with open-. ings 24 and 24 in plates 21. The opaque portions between the slots are located below perforations 38, when the shutteris stationary. so as to prevent all light from passing to the printing numerals. The shutter is mounted upon a rotary hub 66 which turns with shaft 67 in a. bearing 68 at one side of the chamber 56. It is driven intermittently in one direction to move a slot at each step across perforations 38 so that a flash of light from the lamp hereinafter described can pass through the printing images to the film. v I

Inside of shutter 63 is a stationary tube 69 (F ig. 18) which is supported in an end wall ofthe chamber 56. Within this tube is stationarily fastened a block 70 provided with a series of staggered faces 71, each inclined to the axis of the tube and earing a corresponding small inclined mirror 72, the angle of which may be adjusted if desired by means of screws 73, as shown in Fig. 13. The upper side of the tube is cut away at 7% so as to pass light to the perforations 3S and printing images of rings 29, which are situated. in pathway 2 L.

ll hile in the broader as ects of my invention any means for directing aetinic light to mirrors 72 may be employed, I prefer to use a light source in a light-tight casso as not to interfere with the latter. Thus in the drawings. I have shown a casing 75 'located at one side of chamber 56 and provided with an opening 7 6 in the top thereof which connects with said chamber, there being mounted detachably in said casing a small incandescent lamp 77 carried byi a removz ble socket member 3 of well known type. Beneath the lamp 77 I may also employ a concave mirror 79 to directlsome of the rays from lamp 77 upwardly. In one wall of chamber 56, and forming a part,

mg which isoiisct from the path of thefilm thereof, is detachably fastened an inclined mirror 80, a black mask or gasket 81 being located between it and the surrounding walls of (30. Mirror 80 is substantially parallel to mirrors'72' and inclined to'tlie axis- I Consequently, the beams of light from lamp 77 which proceed upwardly through open spaced and dimensioned as to send a sepaf rate beam toward each perforation 3S and the corresponding images 321 beyond.

From cons deration of this structure, it

will be seen that no ac'tinic light can leak out In order that the edge of the film to be printed may be held in proper printing contact with the facets and lmage bearmg plates 32 of rlngs 29, I provlde a presser foot 82, see Figs. 3, 4 andS. This is mount-- ed to oscillate with shaft 83 which is carried in bearings 81 upon one wall of chamber 56, shaft 83 being shown assubstantially parallel to the path of movement of the film through the apparatus. Aspring 85 tends to turn shaft 83 to bring the presser foot 82 in its upper position, and means hereinafter described are employedto move it positively in the opposite oraclampiug position.

Uponone end of shaft 83 is an oscillating arm,86 in which is a retractable pin 87 which reng ages with an independently pivoted part 88 of the presser foot. By retranting pin 87 part 88 is no longer driven by arm 86 and can be independently swung out of theway to permit access to opening 24 in the path- The movable parts of the entire apparatus hereinabove described are driven" in .proper timed relation by mechanism which will now be detailed. Shaft 10 (Fig. 1) is connected by beveled gears 89 with a shaft 90 which, through beveled gears 91, rotates a stub shaft 92 turning the cam 93' thereon.

the lug 95 on which engages the driving periphery of cam 93, said periphery having a gradually rising face-96 and a sudden radial drop shoulder 97. Block 94 is drawn toward the cam by a strong spring 98. Attached to a block 94 and moving therewith is a link rod 99 formed in two parts, said parts being adjustably connected by a turnbuckle 100 to permit the total length to "be changed. This enables the parts of the pawl and ratchet mechanism hereinafter described to be properly adjusted. Rod 99 carries attached thereto the piston 101 of dash-pot 102, the latter being held stationary by a yoke 103 ad-justably' clamped upon pin 104' by means of split bearing 10'?) and bolt 106. The yoke engages the dash-pot by means of slots 107 and pins 108. The dash-pot is provided with an end 109 containing a series of perforations 110 which may be movedinto and out I of registry with perforations 111 in the body of the dash-pot, the end 109 turning relative to the body of the dash-pot upon hub 112,

' and being held in adjusted relation by means ofscrew 113 engaging in groove 114 of said hub. In Fig. 10, the perforations 110, being partially out of alinement with 111 intersect the section plane only slightly and so form small horizontal slots 115 in said view. The outer end of rod 99 is connected through ayoke 116 and pin. 117 with a lever 118 which oscillates shaft 392, the latter being supported by an additional bearing 119 outside of the lever 118. shaft 392 and oscillating therewith is an arm 120 which is provided with a slot 121 engagi ng a pin 122 by means of which it oscillates sector 123 which-is freely rotatable upon the outer end of shaft 67. On the inner end of shaft 392 and oscillating therewith is an arm 393, Fig. -11, provided with a radial slot 394 near one end. in which yoke 44. g

The sector 123 carries a small pawl shaft 124 which is constantly turned by means of spring 125 to press its pawl 126'into working'engagement with. ratchet wheel 127. A

On theouter end of- At an instant when the film same from turning backward or clockwise in Figs. 6, 7 and 8. The ratchet wheel .127 is connected to a cam wheel'130 by means of parallel spaced pins 131, there being one pin for each tooth of the ratchet wheel. The cam isprovided with a series of high spots 132, one high spot being located angularly between each pair of teeth, as shown in Fig. The ratchet wheel 127 and. cam 130 areattached to shaft (37 to rotate therewith. The end of shaft 83. carries an operating'arm 133 which bears at its lower 'end.

a roller 134 engaging the periphery of cam 130, the shape of the cam being such that a rapid oscillation will be given arm 133 during each step through which the cam 130'is rotated.

' The ratchet wheel 127 and the parts at tached thereto are given a rapid movement I ing lighted, the parts are set in motion. The

perforating machine A will draw the film intermittently through the apparatus B.

Since shaft 14' is connected to turn in timed relation to such feeding means and since cam;93 is connected through the above described gearing and shafts with shaft 14, said cam 93 will turn in timed relationwith the forward movement of the film. Cam 93, beginning with the position in Fig. 1, moves rod 99 forwardly on to the right, thereby oscillating shaft 39 and swinging yoke 44 to operate the train of pawls, ratchets, and

gears which change the printing numbers appearing at the printing station or opening 24. This forward movement of 99 andoscillation of lever 118 also swing extension 135 out of locking position. This movement takes place preferably during the advance of the film through a standard distance, say

one foot.

or. there is a dwellin its 'movement, the lug 97 slips off from the high point of cam 93 so that block 94 and rod 99 are pulled suddenly backward to the left in Fig. 1 by spring 98, the dash-pot 102 controlling the speed of the return andcnshioning the action. This causes shaft .39 tov oscillate in the other direction, moving arm 120 clockwise in Fig. 6, thereby oscillating sector 123 and, through'pawl 126, advancing theratchet 127 to the extent of one tooth, ex-

has stopped,

tension 135 beifig brought to the locking position i hdicated in Fig. 8. The advanceof i-atchet127 to the xtent of one tooth rotates shaft 67 sufficiently to bring a slot in the shutter 68 past the perforations 38 in tube 37 thereby permitting a flash of printing light to pass to those printing images 321,

' which are located in alineinent with opening 24, a At approximately the same time that the shutter is being thus actuated, the high part 1320f cam wheel 130 will press arm 133 outwardly, thereby rocking shaft 83 and v pushing presser foot 82 positively downthe broader aspects of my invention, proward to press or clamp the film against the printing characters. This insures a clear image which results from proper printing contact during exposure. At the end .of the short twist given to ratchet 127 and cam 130, the roller 13% will" ride off high part 132, thereby releasing the presser foot which moves upwardly under the influence of the spring 85. The shutter will then be in the position where it cuts off all light rays from the printing images. This cycle of operations is repeated at each reciprocation of rod 99 and consequently a series of consec.utive latent images will be printed at proper intervals along the edges of the film strip 141, Fig. 20. \Vhile the location of the latent images, which are thus impressed upon the film,is not of primary importance in vided such images do not fall within the picture areas, nevertheless'I prefer to place the numbers along an edge of the film where they will remain unaffected by. the subse-. quent perforating operation. My apparatus is, of course, adaptable for use with film which is not perforated, any of the Well known feeding devices for advancing such. 'filmbeing employed.
